Sue sent in a link to Metacritic's Synecdoche, New York page, which itself has links to a stack of reviews, similar to Rotten Tomatoes. It's 67% positive among critics (higher than I expected, and about what I'd hoped), and 73% among users (way higher than I'd have guessed).
Other useful information: publications with green beside their name are publications we care about; yellow and red are now on the black list.
I kid, I kid.
Sue sent that in ages ago, but I've only now gotten around to posting it. For I am lazy.
